Application And Research Of Street Light Communication Security Problem Based On 6LoWPAN Protocol

With the rapid development of the Internet of things technology,embedded technology and computer technology,the urban street lighting system has developed from the initial human-based regional control to the smart networking-based remote control.This novel smart lighting system is more management efficient,operational stable and energy saving than conventional lamps.The most currently used communication technologies in smart lighting system,however,are still highly suffered from practical perspective.Aiming at these problems,this thesis proposed a new technical solution which is more suitable for the future development of the Internet of things and the functional requirements of the street lighting system.In this thesis,a novel street lighting communication system based on 6LoWPAN protocol is engineered.A comparative analysis of the technical peculiarities of couple of commonly used street lighting communication protocols is conducted and considers that the 6LoWPAN protocol is most suitable for the communication technology of the future street lighting system.Based on the communication architecture of the proposed system,its security issue is analyzed in terms of the security encryption and decryption algorithm.The results show that the AES algorithm demonstrates its high performance of system safety and hardware software compatibility.In addition,the AES-CCM algorithm and AES-ECB algorithm are able to be well integrated into the security mechanism of 6LoWPAN communication system,and are suitable for the communication protocol in lighting system.In this thesis,the experimental platform of the street lighting system has been set up and configured.The hardware and software developments of both ending node and gateway of 6LoWPAN system are realized.Based on this,the measurements of its communication quality and security performance are fully conducted,including internal communication experiment of 6LoWPAN system,data security experiment of MAC layer,external communication experiment of 6LoWPAN system and authentication protocol experiment of gateway node.The experimental results show that the 6LoWPAN demonstrates its full performance of communication stability and data safety.Subsequently,the security data communication of street lighting system is achieved with the help of the precision coordination and monitoring of street lights.
